During detection, the workpieces are photographed by the camera, then compared with the qualified products in the database, and the qualified products or products with different defects are classified, and the workpieces are blown into the corresponding material box by the blowing needle.

[0003] In order to facilitate storage and sales, the qualified clamp needs to be packaged, and in order to reduce the packaging cost, the packaging bag can be used for packaging. Because the size of the clamp is small, a plurality of clamps can be put into each packaging bag, and in order to facilitate counting, the number of clamps in each packaging bag needs to be the same. Although the above-mentioned equipment can detect the clamps, manual counting is still needed to ensure that the number of clamps in each packaging bag is the same, and the workload of manual counting is large and errors are easy to occur. UTILITY MODEL CONTENTS

[0004] The utility model intends to provide a kind of clamp detection and packaging machine, to count the qualified clamp when detecting clamp, ensure that the number of clamps in each packaging bag is the same.

[0005] To achieve the above object, the utility model discloses the following technical scheme: the clamp detection packaging machine, including detection unit, detection unit includes camera, carousel and detection power part, detection power part is used for driving the rotation of carousel, and the camera is opposite to the carousel, and the camera is connected with controller, and the controller is equipped with counting module, still be equipped with guide material unit, sealing unit and clamping unit, and the guide material unit includes hopper, guide material subassembly and closed subassembly, and the guide material subassembly includes guide material cylinder and vertical pusher, and the guide material cylinder is located at the lower part of hopper and is slidably connected with hopper, and the lower end of guide material cylinder is lower than the upper end, and the vertical pusher is connected with guide material cylinder and is used to drive the sliding of guide material cylinder, and the closed subassembly includes closing plate and closing piece, and the closing plate is used to close guide material cylinder, and the closing piece is connected with closing plate and is used to drive closing plate to open and close guide material cylinder, and the controller is connected with closing piece and is used to control the opening and closing of closing piece,

[0006] The sealing unit is lower than the guide material cylinder, and the sealing unit includes two sealing subassemblies, and the projections of the two sealing subassemblies along the vertical direction are located on the two sides of the guide material cylinder respectively, and the two sealing subassemblies each include suction cup, heating piece and sealing piece, and the suction cups of the two sealing subassemblies are opposite, and the heating pieces of the two sealing subassemblies are opposite, and the two sealing subassemblies are used to drive the two suction cups to slide transversely respectively.

[0007] The clamping unit is lower than the hopper, and the clamping unit includes two clamping subassemblies, and the connecting line between the two clamping subassemblies is perpendicular to the connecting line between the two closed subassemblies, and each clamping subassembly includes transverse driving piece and clamp, and the transverse driving piece is used to drive the clamp to slide transversely.

[0008] The beneficial effects of the scheme are as follows:

[0009] 1. The camera in the scheme takes a photo of the clamp, and the controller judges whether it is a qualified product according to the image, and when it is judged to be a qualified product, the air blowing needle blows the clamp from the carousel and falls into the hopper for storage, and at the same time, the counting module is controlled to increase by 1, and when the number counted by the counting module reaches the preset value, it proves that the number of qualified products falling into the hopper reaches the required number of a packaging bag, so manual counting is no longer needed, the probability of counting error is reduced, and the workload of manual labor is reduced.

[0010] 2. The closing plate in the scheme can close the guide material cylinder, and when the closing plate is not opened, the clamps to be packaged are stored above the closing plate, and when the lower end of the guide material cylinder is inserted into the packaging bag, the closing plate is opened, and at this time, the clamps fall into the packaging bag from the closing plate, so in the whole packaging process, the clamps fall on the closing plate from the conveying belt first, and then fall into the packaging bag from the closing plate, instead of falling directly from the conveying belt into the packaging bag, and the falling height of the clamps each time is smaller, avoiding that the clamps fall into the packaging bag at too high a speed due to the too large falling height of the clamps, which causes the damage of the packaging bag. At the same time, the impact force between the clamps in the scheme is smaller, effectively avoiding that the buckles on the clamps fall off due to the impact.

[0011] 3. In the process of sealing the last bag, moving the next bag under the guide cylinder and opening the opening, the sealing plate remains closed, the clamps on the conveying belt can continue to be stored in the guide cylinder, when the opening of the next bag is opened and the number of clamps in the guide cylinder basically reaches the requirement, the guide cylinder is slid downward again, and the required number of clamps are put into the bag at one time, that is, the clamps falling from the conveying belt can be installed in the next bag at the same time as the sealing of the last bag, instead of waiting for all the clamps in the last bag to fall out before sealing the last bag and installing the next bag, so that the next clamp can fall from the conveying belt, and the bag does not need to be kept open for a long time, so that all the clamps can be dropped in a short time, and the efficiency of the clamp packaging is effectively improved

[0012] Further, a supporting unit is arranged below the hopper, and the supporting unit comprises a supporting assembly, the supporting assembly comprises a supporting plate and a discharging piece, the supporting plate is arranged below the guide cylinder, and the discharging piece is used to drive the supporting plate to rotate.

[0013] The supporting plate in the scheme can support the bag, so that the bag is not damaged due to excessive weight after the clamps fall into the bag.

[0014] Further, the supporting unit further comprises a vertical adjusting assembly, the vertical adjusting assembly comprises an adjusting frame, a base frame and a screw rod, the adjusting frame is arranged on the base frame and can slide vertically, and the screw rod is arranged on the base frame and is used to drive the adjusting frame to slide vertically.

[0015] The height of the discharging piece and the supporting plate can be adjusted by moving the adjusting frame vertically, so that the scheme is suitable for bags and guide cylinders of different heights.

[0016] Further, the supporting assembly further comprises a connecting rod, one end of the connecting rod is connected with the supporting plate, the middle part of the connecting rod is hinged with the adjusting frame, and the other end of the connecting rod is slidably connected with a rotating shaft, and the rotating shaft is connected with the discharging piece.

[0017] The discharging piece drives the connecting rod to rotate, so that the supporting plate can be tilted and reset, and the structure is simple.

[0018] Further, the supporting plate is V-shaped, and the length of the side of the supporting plate away from the connecting rod is greater than the length of the side of the supporting plate close to the connecting rod.

[0019] The beneficial effects of the scheme are that when the clamps fall into the packaging bag, there is no connection relationship between adjacent clamps, so under the action of gravity, the upper clamps are easy to roll outward and collide with the side wall of the packaging bag, and the pressure between the clamps and the side wall of the packaging bag is large when colliding, and there is still a risk of tearing the packaging bag. The supporting plate in the scheme can limit the clamps in the packaging bag, preventing the upper clamps from rolling down while also avoiding the packaging bag tilting to cause excessive force between the packaging bag and the suction cup, damaging the mouth of the packaging bag or causing it to fall off the suction cup.

[0020] When the packaging bag is heat-sealed, the supporting plate is inclined, and the packaging bag on the supporting plate slides downward along the side wall of the supporting plate away from the connecting rod. The length of the side wall is large, which can guide the packaging bag when it slides to ensure that the packaging bag can slide into the lower collecting frame or the conveying belt connected to the next process.

[0021] Further, the screw is threadedly connected with a nut seat, the adjusting frame is detachably connected with at least two clamping blocks, all the clamping blocks are distributed along the circumference of the nut seat, and the side wall of the nut seat facing the clamping blocks is V-shaped and abuts against the side wall of the nut seat.

[0022] The beneficial effects of the scheme are that the clamping blocks can limit the nut seat, so that the nut seat does not rotate with the screw when the screw rotates. Compared with directly detachably connecting the nut seat with the adjusting frame, the scheme limits the nut seat with the clamping blocks, so that it is not necessary to install bolts or other fasteners on the nut seat, avoiding damage to the strength of the nut seat caused by the fasteners.

[0023] Further, the screw is rotatably connected with a housing, the housing is provided with a downward-opening limiting groove, and the housing is in a downward-opening state and covers all the clamping blocks and is detachably connected with the adjusting frame.

[0024] The beneficial effects of the scheme are that the housing can limit the nut seat from the axial direction to prevent the nut seat from coming out of the clamping blocks.

[0025] Further, the turntable is provided with a blowing needle in communication with the controller.

[0026] The beneficial effects of the scheme are that the controller can automatically control the blowing needle to start, quickly blow the qualified clamps off the turntable, and the operation is simple.

[0027] Further, the turntable and the hopper are provided with a plurality of conveying belts, and the blowing needles are also provided with a plurality of blowing needles, and the plurality of blowing needles correspond one-to-one with the conveying belts.

[0028] The beneficial effects of the scheme are that the conveying belts can better convey the clamps into the hopper.

[0029] Further, one side wall of the hopper is an inclined surface, the inclined surface is located below the conveying belt, and the length of the inclined surface is greater than that of other adjacent side walls of the hopper.

[0030] The beneficial effects of the scheme are that the clamps first fall on the inclined surface from the conveying belt, and then slowly roll into the bottom of the hopper from the inclined surface due to the smaller slope of the inclined surface, so that the collision between the clamps and the bottom of the hopper is smaller, and the deformation of the clamps or the falling of the buckles on the clamps in the packaging process is avoided.

[0038] EMBODIMENT

[0039] The embodiment is basically as shown in the figure, a clamp detection packaging machine comprises a rack, a detection unit, a guide material unit, a sealing unit, a supporting unit and a clamping unit. Figures 1 to 4 The detection unit comprises a camera, the rotating disc 7 and a detection power element, the rotating support 71 is rotationally connected to the rack through a bearing, the detection power element adopts a motor, the detection power element is connected with the rotating support 71 through a shaft coupling, drives the rotating support 71 to rotate, and the rotating disc 7 is annular and is horizontally installed on the rotating support 71 through bolts.

[0040] A camera is arranged above and opposite to the turntable 7, and is used for taking pictures of the clamps placed on the turntable 7. The camera is connected with a controller. In this embodiment, the controller is provided with a counting module. The controller compares the received image with the qualified product, and marks the clamps as qualified products if the shape and size of the clamps are consistent with those of the qualified product and the clamps are marked. The clamps that do not meet the requirements are marked as defective products. The counting module is increased by one every time a qualified product is detected. The detection method is the same as that of the prior art, and will not be described herein. The controller is connected with three air blowing needles. The camera and the three air blowing needles are sequentially arranged along the circumference of the turntable 7, and the air blowing needles are arranged on the inner side of the turntable 7 and horizontally face the outer side of the turntable 7. The first two air blowing needles are used for blowing the qualified products off the turntable 7, so that the clamps pass through the camera and then pass through the first two air blowing needles, and finally pass through the third air blowing needle. The turntable 7 is laterally provided with two conveying belts 8. One end of each of the two conveying belts 8 is opposite to one of the air blowing needles, and the other end extends to the side away from the turntable 7, and is used for conveying the qualified clamps to the material guiding unit.

[0041] The material guiding unit comprises a hopper 1, a material guiding assembly and a closing assembly. The hopper 1 is bolted to the rack. The right side wall of the hopper 1 is an inclined surface 15. In this embodiment, the upper end of the inclined surface 15 is aligned with the conveying belt 8, so that the clamps fall on the inclined surface 15 first when falling off the conveying belt 8, are buffered by the inclined surface 15, and then slide down the inclined surface 15 into the lower part of the hopper 1, thereby further reducing the speed of the clamps falling into the lower part of the hopper 1.

[0042] The material guiding assembly comprises a material guiding cylinder 12 and a vertical pushing member 11. The material guiding cylinder 12 is vertically sleeved on the lower part of the hopper 1. The vertical pushing member 11 comprises two linear actuators. The two linear actuators are bolted to the front and rear sides of the hopper 1. The pushing rod of the vertical pushing member 11 faces downward and is connected to the top of the material guiding cylinder 12 by a bolt, and is used for driving the material guiding cylinder 12 to move vertically. The closing assembly is arranged at the lower end of the material guiding cylinder 12. The closing assembly comprises a closing plate and a closing member. The closing plate is higher than the material guiding cylinder 12 and is laterally arranged on the side of the hopper 1. The closing plate transversely penetrates the left side wall of the hopper 1 and is in gap cooperation with the hopper 1. The closing member also adopts a linear actuator. The pushing rod of the closing member is connected to the closing plate and is used for sliding the closing plate to the right into the hopper 1 to close the material guiding cylinder 12. In this embodiment, the closing member is electrically connected to the controller. When the value of the counting module reaches a preset value, the controller can start the closing member, control the pushing rod of the closing member to retract, and open the hopper 1. After a certain interval of time, the controller controls the pushing rod of the closing member to extend, so that the closing plate re-closes the hopper 1. Specifically, the interval of time is determined by experiments according to the opening at the bottom of the hopper 1 and the number of clamps to be placed in each packaging bag, so that all the clamps in the hopper 1 can fall into the packaging bag within the interval of time, and the closing plate completely closes the hopper 1 before the next clamp on the turntable 7 moves to the air blowing needle.

[0043] The sealing unit is lower than the guide cylinder 12. The sealing unit includes two sealing assemblies, whose vertical projections are located on the left and right sides of the guide cylinder 12 and are symmetrically arranged along the guide cylinder 12. Each sealing assembly includes a heating element 43, a sealing element 41, and multiple suction cups 42. The sealing element 41 uses a linear actuator, and its push rod is horizontally connected to a mounting base 4 via a flange, used to drive the mounting base 4 to slide left and right. The heating element 43 and the multiple suction cups 42 are both mounted on the mounting base 4. Specifically, the multiple suction cups 42 are distributed sequentially from front to back. In this embodiment, the suction cups 42 are connected to air pipes; the heating element 43 is located below the suction cups 42.

[0044] The clamping unit includes two clamping assemblies located on the front and rear sides of the guide cylinder 12, respectively. Each clamping assembly includes a transverse drive 52, a slide rail 5, and a clamp 51. The slide rail 5 is bolted to the frame from left to right. The clamp 51 is mounted on the slide rail 5 and slides in cooperation with it. Specifically, the clamp 51 in this embodiment is existing technology. The two clamps 51 are used to clamp the front and rear ends of the packaging bag opening, moving the opening of the packaging bag between the suction cups 42 of the two sealing assemblies. In actual installation, the height of the clamp 51 is determined according to the position of the suction cups 42, ensuring that the opening of the packaging bag is aligned with the suction cups 42 of the two sealing assemblies when clamping the packaging bag. The transverse drive 52 also uses a linear actuator. The push rod of the transverse drive 52 is connected to the clamp 51 via a flange, driving the clamp 51 to slide along the slide rail 5.

[0045] The support unit includes a support assembly and a vertical adjustment assembly. The vertical adjustment assembly includes an adjustment frame 2, a base frame 3, and a screw 21. The base frame 3 is located below the hopper 1. Vertical rods are inserted vertically through both ends of the base frame 3 via interference fits. The upper ends of the vertical rods are connected to the machine frame by bolts to fix the base frame 3. The adjustment frame 2 is horizontally positioned above the base frame 3. The screw 21 penetrates vertically through the adjustment frame 2 and is clearance-fitted with the adjustment frame 2. Figure 5 As shown, a nut seat 25 is threaded onto the screw 21. Two V-shaped locking blocks 24 are bolted onto the adjusting frame 2. The two locking blocks 24 are located on both sides of the nut seat 25 and abut against it, limiting the movement of the nut seat 25. A housing 22 is fitted onto the screw 21, positioned above the adjusting frame 2, and has a downward-facing limiting groove inside. The housing 22 covers the two clamps and the nut seat 25, and bolts are installed at both ends of the housing 22. The bolts simultaneously penetrate downwards through the locking blocks 24 and are threadedly connected to the adjusting frame 2, thus fixing the housing 22 and the locking blocks 24.

[0046] The lower and upper ends of the screw 21 are connected to the base frame 3 and the machine frame respectively through bearings. The lower part of the screw 21 is keyed to a first bevel gear. A second bevel gear is rotatably mounted on the base frame 3. The second bevel gear meshes with the first bevel gear, and the second bevel gear is coaxially connected to a handle 31. The screw 21 can be rotated more conveniently through the handle 31.

[0047] The support assembly includes a support plate 6, a feeding component 23, and a connecting rod 61, located directly below the guide cylinder 12. Specifically, in this embodiment, the support plate 6 is lower than the sealing assembly and the clamping assembly, used to support the packaging bag falling into the clamp. In this embodiment, the support plate 6 is V-shaped. In actual implementation, the length of the left side wall of the support plate 6 can be greater than the length of the right side wall, so that when the support plate 6 rotates counterclockwise, the left side wall can be in contact with the conveyor belt, allowing the packaging bag on the support plate 6 to slide directly down the left side wall onto the conveyor belt below, further reducing the vibration of the clamp. The middle part of the connecting rod 61 is hinged to the adjusting frame 2, the left end is welded to the right side wall of the support plate 6, and the right end has a strip groove along the axial direction, in which a rotating shaft 62 is slidably connected. The feeding component 23 also uses a linear actuator. The push rod of the feeding component 23 faces downward, and the rotating shaft 62 passes laterally through the push rod of the feeding component 23, so that when the push rod of the feeding component 23 slides upward, it can push the connecting rod 61 to swing counterclockwise.

[0048] The specific implementation process is as follows:

[0049] The clamps to be packaged are placed on turntable 7 and rotate with it, passing sequentially through a camera, the first two air-blowing needles, and the third air-blowing needle. When passing the camera, the camera takes a picture of the clamp and transmits the data to the controller. The controller determines whether the clamp is a qualified or defective product. If the clamp is determined to be defective, the third air-blowing needle blows air when the clamp rotates to align with it, blowing the clamp off the turntable 7. In practice, a defective product basket can be placed below the turntable 7, or defective products can be transported to a conveyor belt in the recycling process for collection; this will not be elaborated further in this embodiment. When the clamp is determined to be qualified, the statistical value of the controller's counting module is incremented by one. When the clamp rotates to a position opposite to the first two air-blowing needles, the air-blowing needle blows air, blowing the clamp from the turntable 7 onto the conveyor belt 8 above the hopper 1, where it is transported by the conveyor belt 8 to the top of the hopper 1.

[0050] The clamp falls from the conveyor belt 8 onto the inclined surface 15, then slides down to the bottom of the hopper 1, where it is held in place by the sealing plate. Simultaneously, the transverse drive 52 drives the clamp 51 to slide to the left, gripping the opening of the packaging bag. The clamp 51 then returns to its original position to the right, holding the opening between the two sealing components. Finally, the sealing component 41 is activated, causing the suction cups 42 of both sealing components to contact the opening of the packaging bag. A negative pressure is then created within the suction cups 42 via an air pipe, adsorbing the left and right sidewalls of the packaging bag. Finally, the sealing component 41 resets the mounting base 4, opening the packaging bag.

[0051] When the value of the counting module reaches the preset value, it proves that the number of clamps in hopper 1 meets the packaging requirements of one bag. Then, the vertical pusher 11 inserts the guide cylinder 12 downwards into the bag, and simultaneously the controller controls the closing plate to slide out of hopper 1, opening the guide cylinder 1, and the clamps fall downwards into the bag. After all the clamps have fallen out, the controller controls the closing plate to slide back into hopper 1, closing the guide cylinder 12, and the value of the counting module is reset to zero. The guide cylinder 12 is then reset upwards, and its lower end detaches from the bag.

[0052] Then, the heating element 43 is activated, and the mounting base 4 is slid towards each other through the sealing element 41 until the two heating elements 43 come into contact, thus heat-sealing the packaging bag. Since the opening of the packaging bag is adsorbed onto the suction cup 42 at this time, the opening of the packaging bag is fully opened, allowing for a more even heat-sealing of the packaging bag.

[0053] After heat sealing, air is introduced into the suction cup 42 through the air pipe, causing the suction cup 42 to no longer adhere to the packaging bag. At the same time, the heating element 43 is turned off, and the mounting base 4 is reset to a direction away from each other, so that the packaging bag is no longer fixed by the sealing component. When the clamp falls into the packaging bag, the bottom of the packaging bag rests on the support plate 6, which protects and supports the clamp, thus preventing the packaging bag from being damaged by excessive weight. When the packaging bag is heat sealed and the mounting base 4 is reset to a direction away from each other, the push rod of the feeding element 23 slides upward, driving the connecting rod 61 to rotate clockwise, causing the support plate 6 to tilt and automatically drop the packaging bag with the clamp onto the support plate 6. In actual implementation, a conveyor belt can be set up below the support plate 6 to transport the packaged packaging bag to the next process or warehouse.

[0054] When a larger packaging bag is needed, turn the handle 31 to rotate the screw 21 and slide the adjusting frame 2 downward to increase the distance between the support plate 6 and the guide cylinder 12. Similarly, when a smaller packaging bag is needed, slide the adjusting frame 2 upward to decrease the distance between the support plate 6 and the guide cylinder 12, ensuring that the support plate 6 can abut against the bottom of the packaging strap when the clamp falls into the packaging bag, thus supporting the packaging bag.

[0055] The above descriptions are merely embodiments of this utility model. Commonly known technical solutions and / or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application should be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
